Problem Solving Learning With Drawing A Diagram Strategy To Improve Mathematical Reflective Thinking Skills

The purpose of this research was to analyze the increase of mathematical reflective thinking skills among students taught by problem-solving learning with drawing a diagram strategy from students who are taught by conventional learning with an expository method. The research method used is a quasi-experiment with a randomized posttest given to the control group design. To take samples, the researcher used cluster random sampling by taking two of the eight classes, one class as a class experiment and the other class as a control class. The result of this research showed that students’ mathematical reflective thinking skills who are taught problem-solving learning with drawing a diagram strategy overall are higher than students who are taught by conventional learning with an expository method. Specifically, this research showed that problem-solving learning with drawing a diagram strategy indicated a huge increase on the evaluation indicator compared with the other indicators.
